ADJUSTABLE GLID'ER FOR FURNITURE LEGS.

Application filed March 28, 1928.

My invention relates to an adjustable glider to be placed at the end of a leg for furniture for the purpose of permitting the easy movement of the furniture over a floor, while at the same time being made adjustable to accurately compensate for any unevenness which may exist in the lengths of the legs or in the surface of the floor, thus making it possible to quickly and easily adjust said device so as to eliminate any teetering movement in said furniture. I accomplish this by the use of an eccentric foot or glider member mounted in the end of the leg, with means for easily locking eccentric glider or foot in such adjusted position.

In order to explain my invention, I have shown on the accompanying sheet of drawings one practical embodiment of the invention, which I will now describe in detail.

In the drawings, Fig. 1 is a side elevation of a leg for furniture, showing my invention applied thereto, the adjusting mechanism being shown through a cut-away part of the leg; and

F igure2 is a vertical sectional view through the lower end of the leg, showing the invention more in 'detail.

Referring now in detail to the drawings, I will describe the particular embodiment of my invention shown for illustrative purposes.

A glider member 3 is pivotally mounted on a pin 4, through lugs or bosses 5, 5, on a plate 6, through which said glider swings on its pivot pin 4. Said glider has an eccentric portion 3 of rounded form and smooth so as to move freely upona floor surface, and it alsohas a concentric ratchet portion 3", also moving about the pivot pin 4, the ratchet portion being set into the lower end of a leg L, which is bored, as at 7, to receive the concentric portion of said glider 3. The leg is further bored, as at 8, for a part of its length, to receive therein a flanged member 9, through which and up through the bore 8, is a rod 10, provided at its upper end with a lever 11,

pivotally mounted in a face plate 12, set into the face of said leg L, and having a slot therethrough and through which said lever proj ects, substantially as shown. The upper end of said rod 10, is pivotally attached, as at 13, to said lever, whereby the movement of the lever 11, from the down or normal position, to the raised position, shown in light broken lines, raises said rod 10, for a purpose now to be described.

At the lower end of said rod 10, is mounterial No. 265,351.

ed a member or pawl 14, the lower end of which is provided with a toothed surface interfitting with the concentric ratchet portion 3 of said glider 3, so that when said rod 10 is raised, saidmember 14 is disengaged from said ratchet member andv said mitted to turn on its pivot to centric portion 3 up or down, as desired, to lengthen or shorten the total length of the table or other furniture leg. A coiled spring move the ec- 15 is placed on said rod, between said member 14 and-said flanged member 9, to nor mally hold said member 14 down in engagement with said glider 3.

It isto be noted that any upward pressure on the glider 3, tends to turn the eccentric portion 3 about the pivot pin 4, and that the transmitted pressure from the ratchet portion 3 which is concentric with the pivot pin 4, is laterally on said pawl or member 14, and is slight, for the reason that the greater part of the pressure on the glider is taken by the pivot pin 4.

While it is not considered necessary from actual tests, I have shown a filler member 16, set into the bore 8, and through whichthe pawl or member 14 moves.

Thus it will be seen, that I have provided a simple, practical and economical adjustable glider for furniture, and while changes can be made therein without departing from the spirit of my invention, I do not limit the invention to the particular showing made for illustrative purposes, except as I maybe limited by the hereto appended claims.

I claim:

- 1. An adjustable 'lider for furniture legs including an eccentrically mounted portion forming the glider proper and a concentric ratchet portion with a common pivotal support, and means for interlockingwith the concentric ratchet portion to hold the eccentric portion in different positions of adjustment about its pivot.

2. An adjustable glider for furniture legs comprising a pivotally mounted element having an eccentric portion and a concentric ratchet portion turning about a common pivotal mounting, the concentric ratchet portion extended up into the leg with the'eccentric portion projecting therefrom, and means coacting with the ratchet portion to hold said element in adjusted positions.

3. An adjustable glider of the character referred to including in combination a plate, an element pivotally mounted to swing thereglider is per- 7 through and having an eccentric glider portion projecting from one side of said plate and a concentric portion projecting from the other side of said plate and adapted to be extended up into the leg of furniture, and a reciprocating member adapted to interlock with the concentric portion of said element to hold it from turning on its pivot, and means for operating said reciprocating member.

4. An adjustable glider including in com bination a support, an element pivotally mounted therein,said element having a glider portion eccentric relative to said pivot and a concentric portion, and means "for interlocking with said concentric portion for holding the eccentric glider portion in adjusted position.

5. An adjustable glider for furniture including in combination a support, an element pivotally mounted therein and having a portion which is eccentric relative to said pivot and positioned to form a glider, support, and a portion extended up into said furniture and turning with said glider portion, and means for interlocking with said portion to prevent it from turning, whereby to interlock said glider portion in different positions of adjustment. v

6. In combination with a furniture leg, a supportin member to be secured to the lower end of said leg, an element pivotally mounted in said supporting member, ing an eccentric portion projecting downwardly to serve as a glider support, said element having a portion projecting up into said leg and turning with said element, and a movable member in said leg adapted to interlock with said latter portion to lock it in different positions ofadjustment about its pivotal mounting.
